The Hindustan Times reports a source as saying: "Priyanka has been interacting with the international media as part of the promotions for a while now. As a result, people in America now have a fair idea of who she is. Probably that's why she was invited. The song seems to have got her a lot of mainstream popularity."

The actress was photographed with X Factor USA judge Simon Cowell and One Direction, who were performing on the show.

Posting the picture on Twitter, Chopra wrote: " A fun evening for @priyankachopra with @onedirection & @simoncowell on the sets of X Factor USA."
